Delta's new TUMI amenity kits.Flickr/DeltaOn Wednesday, Delta unveiled the new TUMI amenity kits for its international and long-haul domestic flights. The refreshed amenity kits will debut on September 1 with various versions available in all of its cabin classes.

"Every detail incorporated into our TUMI amenity kit has been thoughtfully selected with our customers' needs and preferences in mind - no matter how big or small," Delta's senior vice president for in-flight service, Allison Ausband said in a statement. "We are excited to offer customers the ability to monogram their amenity kits and create a personalized souvenir to take with them as they jet-set across the globe."

For the airline's Delta One premium cabin, the kits feature TUMI cases with skin care products from Kiehl's to create what it calls a "spa-like experience in the sky." The Delta One kit features Kiehl's Lip Baum #1, grapefruit-scented lotion with aloe vera and oatmeal, a dental kit, a TUMI eye mask, socks, ear plugs and more.

For international flights departing the US, passengers will receive the kit in a silver hard-sided TUMI case, while flights headed for the US will get the kit in a soft-sided TUMI case. Certain transcontinental flights from Boston, New York, and Washington D.C. on the east coast to Los Angeles and San Francisco will also be equipped with the kits.
